PURPOSE:To make the work of replacement of engine oil operable independently or simultaneously respectively, by means of arranging the drain mechanism and the filling mechanism of engine oil within a single case. CONSTITUTION:The drain mechanism of engine oil is such that the other end of a hose 4, having a flexible oil suction tube 5 at its point end, be connected to the suction side of a pump 2, with the delivery side of the pump 2 linked to a waste oil dirt indicator 6 through a tube 7, to make an outflow tube 9, from the indicator 6, opening in a transparent vessel 10 for collecting the waste oil. While the mechanism of filling an engine oil is such that a suction tube 18, made opening in the bottom part of a new oil transparent vessel 17, be coupled to a tube 20, at the suction side of a pump 11, through a coupling 19, with a delivery tube of the pump 11 linked to an oil filling nozzle valve 16 through a tube 21, a flow meter 14 and a hose 15. |
